. fot.Philadeljiihia, in the county ot Philadel- ,pliia and State oiVPennsylvana, have invented an Improvement in Stop Bones,` ot

yW-liich the following isl a speciiication.

ih/ty invention relates to stop hores, and it f construction et inea-ns for permitting ready .att ehinent and, removal yof a stop hox `cover andy for retaining thecover in place atter it has heenlattached. v

To x these L and otliei' ent s my invention comprises; the combination andarrangeiiient l of parts as hereinafter desciihedand illustrated in then drawing and `partieularly pointed'ont :inthe claims. Itwill he understood, however, that changes I in the` details ,oi construction pinay he made -within the scope of; thecleiins without departing ilifoin .lthefsaid invention las the saine inayf he .de-

, has forl itsfgeneral object to,l provide a novel 5 for the lGin `the thickenedportion 3 Referring toithe drawing: 1 designates a stop loof; which is provided With an in- `niardly extending` flange 2, the outer upper portion oievhich is thickened, `asindicated 11:13, so as to provide a shoulder nt iiwthin which the outer edge oi a cover isfadapted toire seated. V llheilovrer outeiw edge of the said cover is adapted to rest upon the portion oit' the flange which; projects inwardly `beyond the thickened portion 3 In 'order to ennhle the lifting' of the cover purpose oit removing the saine from I'heve provided notches-or slots of; the flange Q which notches or slots, when the cover is in place upon the oorfai'e in registry with `notchesI or slotslt) upon the underneath side ot' the outer edge ot thel cover ln the the hor,

l cOimt-rurtion as shown the notches `G iind the notches 10 are located in oppositeljv disposed diametr-ic `relation to each other 'lilhel portion ot' the lliange 2 which projects beyond the thickened portion 3 is provided With notches or slots 12 `and 13 through which the outwardly projecting end poi' tions `11i and 15 ot the projections 1G and 17 rwhich `depend from the cover Vfr are .adapted to pass eitheiwi'or the .purpose of attaching' the coverjto the body-ot the hoz:

korior the purpose of removing the sinne therefrom. The projection 15 isprovided ywith a radially extending cut-out `portion as indicated; at 18. The lower` and outwardly projectingI end portion 1i ot. thc dependingprojection `16 is achipted `to enter cess onto `a seat provided npon n hoss or projection 2O upon the inner-side ot the box l below the flange 2. The lower side of the said recess is provided with a relatively .shallow `portion or notch 21 and with a 1 deeper recessed or notched portion 22, which portions are separated hy a shoulderp.

The lower outwardly extending end por- 1 tion 15 ot' the projection 17 isadapted, when 4the lid or @over is iirstplaced imposition, -to restffupon the upper-side oi' a projectioirfZ in oppositely disposed relation to the vprojection 20. `The said projection 25 is provided with a cut-ont portion or notcln asindicated `at 2", the presence of which forms a shoulder ZT, as indicated. The seats upon the vertical Walls of the box which are adapted to be occupied by the projections 16 and 17 upon the cover when the latter is in position may be provided in any desired'suitable manner.

In the placing of a lid or cover in position the lower outwardly extending end portions of the projections 16 and 17 are inserted through the notches or slots 12 and 1:5 respectively so that the lower edge of the projection 16 will rest upon the upper side of the portion 21, while the lower edge of the projection 17 will rest upon the upper side of the projection 25. The lid or cover is then turned to the right so as to move or carry the outwardly extending projection 14 of the depending lug or projection 16 onto the portion 22 of the lug or projection 20 with one edge thereof bearing against the shoulder 23. At the same time the lower outwardly extending end portion of the lug 17 is moved tothe left so as to cause the cut-out portion 18 of the projectionA 17 to engage the shoulder 27 `of the proj ection 25.

It will be seen that when the lid or cover is in this position it cannot be turned to the left for the purposeY of removing the same without first lifting it from the flange 2, and it will also be apparent that the said lid or cover cannot be lifted vertically upwardly so as to remove the same from the box because of the fact that when placed in linal position the outwardly extending projections 14 and 15 of the depending lugs or projections 16 and 17 are located or situated underneath portions of the flange 2 adjacent the notches 12 and 13.

It will be seen-that by my invention I have provided a stop box construction in which the lid or cover may be readily placed upon the box and removed therefrom. It will also be seen that when the lid or cover is once placed in position it is practically impossible for the same to be dislocated or removed accidentally.

Having thus described my invention, what I claim and desire to secure by Letters Patj ent is: f

y1. In a stop box, the combination of a box having a flange adjacent its upperkend and extending inwardly, which flangeis pro-l vided with notches extending therethrough and the said box also having lugs or projec-v tions located below the said flange, which lugs or projections are provided withv notches in their upper edges which form vertical shoulders, and a cover for the said box, which cover is provided with depending projections the lower edges of whichk terminate in outwardly projecting extensions which are adapted to engage said shoulders whereby the said cover is prevented from turning in one direction until it is lifted vertically a distance suflicient to disengage the said projecting extensions from said shoulders.

2. In a stop box, the combination ofy a box having an inwardly extending flange situated adjacent its upper end, which flange is provided with notches located at intervals therein, projections situated upon the inner side of the said box below the said flange, which projections are in cc-operative relation to the said notches, and each of the said projections being provided with horizontal surfaces upon their upper sides located iii different planes and separated from each other by substantially vertical shoulders, and a cover provided with depending projections the lower edges of which terminate in outwardly extending portions which are adapted to engage the shoulders separating the horizontal surfaces of the said inwardly extending projections, substantially as devbeing provided with-projections upon the inner side thereof below the notches through the said flange, oneof` the said projections beingprovided .with a notch the bottom of which comprises surfaces located in diiferent horizontal planes, which surfaces are separated ,by a shoulder, and the other of said projections being provided with a cutout portion in its upper side, which cut-out portion forms a shoulder, and a cover provided withy depending lugs or projections having outwardly'and radially extending projections at their lower ends which latter projections aie adapted to engage the shoulders upon the projections upon the inner side of the said box, substantially as described.

11. In a stop box, the combination of a box having an inwardly extending flange like portion, the outer' portion of which is thickened to provide an inner ledge, the said thickened portion being provided with notches at intervals therein, and the said ledge being providedw'ith slots at intervals therein, and the said box being provided with projections situated below Vthe said slots, which projections are provided with notches in their upper sides, and a cover having depending lugs the lower ends of which are provided with outwardly extending projections which are adapted to enter the said slots and to engage the notches in the projections upon the said box, substantially as described.

5. In a stop box, the combination of av box having an inwardly extending ilange located at its upper end, which flange is provided with notches located at intervals therein, seats located upon the inner side of the said box below'the said flange, which seats are in' cooperative relation with the said notches and each of the said seats being provided with horizontal surfaces upon their upper sides located in different planes `and separated by substantially vertical shoulders, and a cover provided With depending projections7 the lower edges of which terminate in outwardly extending portions which are adapted to engage the said shoulders whereby turning of the said cover horizontally in one direction is prevented until it is lifted vertically so as to disengage the said outwardly extending por- 10 tions of the said projections from the said shoulders.

In testimony that I claim the foregoing as my invention, I have hereunto signed my naine this 26th day of October, 1923.
